You can project a texture onto another object by placing a light behind it, and making the texture the light passes through semi-transparent in a RayMaker rendering.
When creating your image based texture, make sure to adjust your transparency setting in the texture editing dialog. The more transparent the texture, the more light will pass through your 3D polygon, acting exactly like an overhead transparency.
2. Place a light source behind the 3D polygon.
All light sources will work, however a spotlight may give you the best results.
3. Create an object in front of your light source to receive your projected image.
4. Make sure Transparency is checked in the RayMaker rendering preferences.
5. Select LightWorks RayMaker from the Rendering menu.
